Which of the following statements is true regarding millipedes and centipedes?

Millipedes are known to be scavengers, primarily feeding on decaying plant material, while centipedes are predatory and actively hunt for their prey, which typically includes insects and other small arthropods. The distinction here is significant as it highlights the differing lifestyles and ecological roles of these two groups.

Centipedes are generally solitary creatures that rely on their venomous bite to immobilize their prey before consumption. This predatory nature makes their survival strategy fundamentally different from that of millipedes. In contrast, while millipedes are often found in groups, this behavior is not indicative of sociality in a cooperative sense; they are more accurately described as communal, gathering in large numbers primarily due to their preference for moist environments, which can aid in achieving better survival rates against desiccation.

Understanding these characteristics reveals a clearer picture of their behavior and habitat. Therefore, the statement that centipedes are predators and millipedes are social captures the essence of their respective ecological niches accurately.
